The human genome encompasses some 2,000 proteins that utilize adenosine 5′-triphosphate (ATP) in one way or another and some 500 of these encode for protein kinases, i.e the protein-tyrosine and protein-serine/threonine kinases, that share a catalytic domain conserved in sequence and structure but which are notably different in how there catalysis is regulated. Substrate phosphorylation by these enzymes is nature's predominant molecular way of organizing cellular signal transduction and regulating biochemical processes in general. It is not surprising, therefore, that abnormal phosphorylation of cellular proteins is a hallmark of disease and that there is a growing interest in the use of kinase inhibitors as drugs for therapeutic intervention in may disease states such as cancer, diabetes, inflammation and arthritis.

In fact the search for such agents has recently culminated in the approval of the first kinase inhibitor drugs Herceptin® (Trastuzumab) and Gleevec™ (imatinib mesylate) for medical use. Herceptin® (Trastuzumab) is targeted against Her2/neu, a receptor tyrosine kinase found to be amplified up to 100-fold in about 30% of patients with invasive breast cancer. In clinical trials Herceptin® (Trastuzumab) proved to have anti-tumour activity against breast cancer (Review by L. K. Shawer et al, “Smart Drugs: Tyrosine kinase inhibitors in cancer therapy”, 2002, Cancer Cell Vol. 1, 117), and accordingly provided the proof of principle for therapy targeted to receptor tyrosine kinases. The second example, Gleevec™ (imatinib mesylate), is targeted against the abelson tyrosine kinase (BcR-Abl), a constitutively active cytoplasmic tyrosine kinase present in virtually all patients with chronic myelogenous leukaemia (CML) and 15% to 30% of adult patients with acute lymphoblastic leukaemia. In clinical trials Gleevec™ (imatinib mesylate) showed a spectacular efficacy with minimal side effects that led to an approval within 3 months of submission. The speed of passage of this agent through clinical trials and regulatory review has become a case study in rapid drug development (Drucker B. J. & Lydon N., “Lessons learned from the development of an Abl tyrosine kinase inhibitor for chronic myelogenous leukaemia.”, 2000, J. Clin. Invest. 105, 3).

In addition to the above, EGF receptor tyrosine kinases has been shown to be implicated in non-malignant proliferative disorders such as psoriasis (Elder et al., Science, 1989, 243; 811). It is therefore expected that inhibitors of EGF type receptor tyrosine kinases will be useful in the treatment of non-malignant diseases of excessive cellular proliferation such as psoriasis, benign prostatic hypertrophy, atherosclerosis and restenosis.

It is accordingly an object of the present invention to provide further kinase inhibitors useful in the manufacture of medicaments, in particular in the manufacture of medicaments for the treatment of cell proliferative related disorders.

This invention relates to 2,4 (4,6) pyrimidine derived macrocycles of formula (I) that have been found to have kinase inhibitory activity. In particular, the compounds of the present invention were found to have an anti-proliferative activity and are accordingly useful in methods of treatment of the human or animal body, for example in the manufacture of medicaments for use in hyper proliferative disorders such as atherosclerosis, restenosis and cancer. The invention also relates to processes for the manufacture of said pyrimidine derivatives, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments of use in the production of anti-proliferative effect.

For those compounds where X¹ represents —O—, X² represents a direct bond and Y represents C₁₋₆alkyl-NH—CO—, the suitable substituted anilines of formula (III^(d)) are generally prepared according to reaction scheme 11.

In a first step the known 2-nitro-benzoic acids (XXIII) are amidated to the intermediates of formula (XXIV) under art known conditions, for example, using a hydroxylated amine of formula (XIX′) that is added dropwise to a mixture of (XXIII) in CH₂Cl₂ in the presence of 1,1′carbonylbis-1H-imidazole.

Next the primary free alcohol is protected using art known procedures, for example, using an esterification reaction with acetic anhydride in the presence of pyridine.

The thus obtained intermediate of formula (XXV) is subsequently reduced according to standard conditions, for example, using iron/acetic acid to yield the substituted anilines of formula (III^(d)).

For those compounds where X² represents a direct bond the suitable substituted anilines of formula (III^(e)) are generally prepared according to reaction scheme 12.

In a first step the known 2-nitro-benzaldehydes (XIII) are alkenated to the intermediates of formula (XXVII) under art known conditions, for example, using the Wittig Reaction with the appropriate phosphonium salt of formula (XXVI).

Following esterification of the free carboxylic acid under standard conditions for example, using ethanol under acidic conditions, the intermediate of formula (XXVIII) are reduced to yield the desired substituted anilines of formula (III^(e)).

More specific examples for the synthesis of compounds of formula (I) are provided in the examples hereinafter.

Where necessary or desired, any one or more of the following further steps in any order may be performed:

-   (i) removing any remaining protecting group(s); -   (ii) converting a compound of formula (I) or a protected form     thereof into a further compound of formula (I) or a protected form     thereof; -   (iii) converting a compound of formula (I) or a protected form     thereof into a N-oxide, a salt, a quaternary amine or a solvate of a     compound of formula (I) or a protected form thereof; -   (iv) converting a N-oxide, a salt, a quaternary amine or a solvate     of a compound of formula (I) or a protected form thereof into a     compound of formula (I) or a protected form thereof; -   (v) converting a N-oxide, a salt, a quaternary amine or a solvate of     a compound of formula (I) or a protected form thereof into another     N-oxide, a pharmaceutically acceptable addition salt a quaternary     amine or a solvate of a compound of formula (I) or a protected form     thereof; -   (vi) where the compound of formula (I) is obtained as a mixture     of (R) and (S) enantiomers resolving the mixture to obtain the     desired enantiomer.

Compounds of formula (I), N-oxides, addition salts, quaternary amines and stereochemical isomeric forms thereof can be converted into further compounds according to the invention using procedures known in the art.

It will be appreciated by those skilled in the art that in the processes described above the functional groups of intermediate compounds may need to be blocked by protecting groups.

Functional groups, which are desirable to protect, include hydroxy, amino and carboxylic acid. Suitable protecting groups for hydroxy include trialkylsilyl groups (e.g. tert-butyldimethylsilyl, tert-butyldiphenylsilyl or trimethylsilyl), benzyl and tetrahydropyranyl. Suitable protecting groups for amino include tert-butyloxycarbonyl or benzyloxycarbonyl. Suitable protecting groups for carboxylic acid include C₍₁₋₆₎alkyl or benzyl esters.

The protection and deprotection of functional groups may take place before or after a reaction step. The use of protecting groups is fully described in ‘Protective Groups in Organic Synthesis’ 2^(nd) edition, T W Greene & P G M Wutz, Wiley Interscience (1991).

Additionally, the N-atoms in compounds of formula (I) can be methylated by art-known methods using CH₃—I in a suitable solvent such as, for example 2-propanone, tetrahydrofuran or dimethylformamide.

The compounds of formula (I) can also be converted into each other following art—

known procedures of functional group transformation of which some examples are mentioned hereinafter.

The compounds of formula (I) may also be converted to the corresponding N-oxide forms following art-known procedures for converting a trivalent nitrogen into its N-oxide form. Said N-oxidation reaction may generally be carried out by reacting the starting material of formula (I) with 3-phenyl-2-(phenylsulfonyl)oxaziridine or with an appropriate organic or inorganic peroxide. Appropriate inorganic peroxides comprise, for example, hydrogen peroxide, alkali metal or earth alkaline metal peroxides, e.g. sodium peroxide, potassium peroxide; appropriate organic peroxides may comprise peroxy acids such as, for example, benzenecarboperoxoic acid or halo substituted benzenecarboperoxoic acid, e.g. 3-chlorobenzenecarboperoxoic acid, peroxoalkanoic acids, e.g. peroxoacetic acid, alkylhydroperoxides, e.g. t-butyl hydroperoxide. Suitable solvents are, for example, water, lower alkanols, e.g. ethanol and the like, hydrocarbons, e.g. toluene, ketones, e.g. 2-butanone, halogenated hydrocarbons, e.g. dichloromethane, and mixtures of such solvents.

Some of the compounds of formula (I) and some of the intermediates in the present invention may contain an asymmetric carbon atom. Pure stereochemically isomeric forms of said compounds and said intermediates can be obtained by the application of art-known procedures. For example, diastereoisomers can be separated by physical methods such as selective crystallization or chromatographic techniques, e.g. counter current distribution, liquid chromatography and the like methods. Enantiomers can be obtained from racemic mixtures by first converting said racemic mixtures with suitable resolving agents such as, for example, chiral acids, to mixtures of diastereomeric salts or compounds; then physically separating said mixtures of diastereomeric salts or compounds by, for example, selective crystallization or chromatographic techniques, e.g. liquid chromatography and the like methods; and finally converting said separated diastereomeric salts or compounds into the corresponding enantiomers. Pure stereochemically isomeric forms may also be obtained from the pure stereochemically isomeric forms of the appropriate intermediates and starting materials, provided that the intervening reactions occur stereospecifically.

An alternative manner of separating the enantiomeric forms of the compounds of formula (I) and intermediates involves liquid chromatography, in particular liquid chromatography using a chiral stationary phase.

Some of the intermediates and starting materials as used in the reaction procedures mentioned hereinabove are known compounds and may be commercially available or may be prepared according to art-known procedures. However, in the synthesis of the compounds of formula (I), the present invention further provides;

As described in the experimental part hereinafter, the growth inhibitory effect and anti-tumour activity of the present compounds has been demonstrated in vitro, in enzymatic assays on the receptor tyrosine kinases EGFR, ErbB2, ErbB4, F1T3, BLK or the Sar kinase family such as for example Lyn, Yes cSRC. In an alternative assay, the growth inhibitory effect of the compounds was tested on a number of carcinamo cell lines, in particular in the ovarian carcinoma cell line SKOV3 and the squamous carcinoma cell line A431 using art known cytotoxicity assays such as MTT.

Accordingly, the present invention provides the compounds of formula (I) and their pharmaceutically acceptable N-oxides, addition salts, quaternary amines and stereochemically isomeric forms for use in therapy. More particular in the treatment or prevention of cell proliferation mediated diseases. The compounds of formula (I) and their pharmaceutically acceptable N-oxides, addition salts, quaternary amines and the stereochemically isomeric forms may hereinafter be referred to as compounds according to the invention.

Disorders for which the compounds according to the invention are particularly useful are atherosclerosis, restenosis, cancer and diabetic complications e.g. retinopathy.

In view of the utility of the compounds according to the invention, there is provided a method of treating a cell proliferative disorder such as atherosclerosis, restenosis and cancer, the method comprising administering to an animal in need of such treatment, for example, a mammal including humans, suffering from a cell proliferative disorder, a therapeutically effective amount of a compound according to the present invention.

Said method comprising the systemic or topical administration of an effective amount of a compound according to the invention, to animals, including humans. One skilled in the art will recognize that a therapeutically effective amount of the kinase inhibitors of the present invention is the amount sufficient to induce the growth inhibitory effect and that this amount varies inter alia, depending on the size, the type of the neoplasia, the concentration of the compound in the therapeutic formulation, and the condition of the patient. Generally, an amount of kianse inhibitor to be administered as a therapeutic agent for treating cell proliferative disorder such as atherosclerosis, restenosis and cancer, will be determined on a case by case by an attending physician.

Generally, a suitable dose is one that results in a concentration of the kinase inhibitor at the treatment site in the range of 0.5 nM to 200 μM, and more usually 5 nM to 10 μM. To obtain these treatment concentrations, a patient in need of treatment likely will be administered between 0.01 mg/kg to 500 mg/kg body weight, in particular from 10 mg/kg to 250 mg/kg body weight. As noted above, the above amounts may vary on a case-by-case basis. In these methods of treatment the compounds according to the invention are preferably formulated prior to admission. As described herein below, suitable pharmaceutical formulations are prepared by known procedures using well known and readily available ingredients.

In yet a further aspect, the present invention provides the use of the compounds according to the invention in the manufacture of a medicament for treating any of the aforementioned cell proliferative disorders or indications.

The amount of a compound according to the present invention, also referred to here as the active ingredient, which is required to achieve a therapeutical effect will be, of course, vary with the particular compound, the route of administration, the age and condition of the recipient, and the particular disorder or disease being treated. A suitable daily dose would be from 0.01 mg/kg to 500 mg/kg body weight, in particular from 10 mg/kg to 250 mg/kg body weight. A method of treatment may also include administering the active ingredient on a regimen of between one and four intakes per day.

While it is possible for the active ingredient to be administered alone, it is preferable to present it as a pharmaceutical composition. Accordingly, the present invention further provides a pharmaceutical composition comprising a compound according to the present invention, together with a pharmaceutically acceptable carrier or diluent. The carrier or diluent must be “acceptable” in the sense of being compatible with the other ingredients of the composition and not deleterious to the recipients thereof.

The pharmaceutical compositions of this invention may be prepared by any methods well known in the art of pharmacy, for example, using methods such as those described in Gennaro et al. Remington's Pharmaceutical Sciences (18^(th) ed., Mack Publishing Company, 1990, see especially Part 8: Pharmaceutical preparations and their Manufacture). A therapeutically effective amount of the particular compound, in base form or addition salt form, as the active ingredient is combined in intimate admixture with a pharmaceutically acceptable carrier, which may take a wide variety of forms depending on the form of preparation desired for administration. These pharmaceutical compositions are desirably in unitary dosage form suitable, preferably, for systemic administration such as oral, percutaneous or parenteral administration; or topical administration such as via inhalation, a nose spray, eye drops or via a cream, gel, shampoo or the like. For example, in preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as suspensions, syrups, elixirs and solutions: or solid carriers such as starches, sugars, kaolin, lubricants, binders, disintegrating agents and the like in the case of powders, pills, capsules and tablets. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. For parenteral compositions, the carrier will usually comprise sterile water, at least in large part, though other ingredients, for example, to aid solubility, may be included. Injectable solutions, for example, may be prepared in which the carrier comprises saline solution, glucose solution or a mixture of saline and glucose solution. Injectable suspensions may also be prepared in which case appropriate liquid carriers, suspending agents and the like may be employed. In the compositions suitable for percutaneous administration, the carrier optionally comprises a penetration enhancing agent and/or a suitable wettable agent, optionally combined with suitable additives of any nature in minor proportions, which additives do not cause any significant deleterious effects on the skin. Said additives may facilitate the administration to the skin and/or may be helpful for preparing the desired compositions. These compositions may be administered in various ways, e.g., as a transdermal patch, as a spot-on or as an ointment.

It is especially advantageous to formulate the aforementioned pharmaceutical compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used in the specification and claims herein refers to physically discrete units suitable as unitary dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Examples of such dosage unit forms are tablets (including scored or coated tablets), capsules, pills, powder packets, wafers, injectable solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and segregated multiples thereof.

DIPEA (0.012 mol) was added to a solution of intermediate 44 (0.002 mol) in 50 mL of dry DMF (q.s.) and then this solution was added dropwise to a mixture of HBTU (0.006 mol) in 150 mL of dry DMF (q.s.). The resulting mixture was stirred for 30 minutes at room temperature and the solvent was evaporated. PS-NMe₃(+)HCO₃(−) (Novabiochem, cat. 01-64-0419) was added and the mixture was shaken overnight. After filtration, Silica-SO₃H (Acros, cat. 360220050) (0.016 mol) was added portionwise to “catch” the product, then the reaction mixture was filtered over a plug of silica gel and washed with DCM/MeOH (9:1). The product was then released by washing with DCM/7 N NH₃ in MeOH (9:1) and, upon evaporation of the solvent, triturated with MeOH. Filtration of the precipitate provided 0.1024 g of the pure product. The mother liquor and washings of the silica gel were combined and purified by reversed phase HPLC (NH₄OAc buffer) yielding a second batch of product, yielding 0.0581 g of compound 11.

The compound could be isolated in two ways:

-   -   1. Catch and release: The solvent was concentrated to about 100         mL after which PS-NMe₃(+)HCO₃(−) (Novabiochem, cat. 01-64-0419)         (0.012 mol) was added. The resulting suspension was shaken         overnight to scavenge 1-hydroxybenzotriazole (HOBt). After         filtration and washing with DMF, Silica-SO₃H (Acros,         cat. 360220050) (0.016 mol) was added portionwise to catch the         compound, then the reaction mixture was filtered over silica gel         and washed with DCM/MeOH (90/10). The desired product was then         released by washing with 10% 7 N NH₃/MeOH in DCM. After         evaporation of the solvent, MeOH was added, and the resulting         precipitate was filtered off giving pure compound 11 (0.1024 g,         12% from intermediate 63).

Reversed Phase HPLC: Alternatively, the reaction mixture after macrocyclization can be evaporated to dryness and directly purified by high-performance liquid chromatography (NH₄OAc buffer). In this case compound 11 can be obtained in 20% yield from intermediate 63, mp. 286.3-288.1° C.

C. Pharmacological Examples

The in vitro inhibition of a panel of kinases was assessed using either the glass-fiber filter technology as described by Davies, S. P. et al., Biochem J. (2000), 351; p. 95-105.

In the glass-fiber filter technology the activity of the kinase of interest is measured using an appropriate substrate that is incubated with the aforementioned kinase protein in the presence of (³³P) radiolabeled ATP. (³³P) Phosporylation of the substrate is subsequently measured as radioactivity bound on a glassfiber-filter.

DETAILED DESCRIPTION

All kinases are pre-diluted to a 10× working concentration prior to addition into the assay. The composition of the dilution buffer for each kinase is detailed below.

Buffer Composition Kinase(s) 50 mM Tris pH 7.5, 0.1 mM EGTA, CSK, Lyn 0.1 mM Na3VO4, 0.1%-mercaptoethanol, 1 mg/ml BSA 20 mM MOPS pH 7.0, 1 mM Abl, EGFR, Fes, Fms, Flt3, Fyn, EDTA, GSK3, Lck, Yes 0.1%-mercaptoethanol, 0.01% Brij-35, 5% glycerol, 1 mg/ml BSA

All substrates are dissolved and diluted to working stocks in de-ionised water, apart from histone H1 (10× working stock in 20 mM MOPS pH 7.4), PDKtide (10× working stock in 50 mM Tris pH 7.0) and ATF2 (which is typically stored at a 20× working stock in 50 mM Tris pH 7.5, 150 mM NaCl, 0.1 mM EGTA, 0.03% Brij-35, 50% glycerol, 1 mM benzamidine, 0.2 mM PMSF and 0.1% β-mercaptoethanol).

Example C.12 In Vitro Inhibition of EGFR (Flash Plate Assay)

The in vitro inhibition of EGFR was assessed using either the Flash Plate technology or the glass-fiber filter technology as described by Davies, S. P. et al., Biochem J. (2000), 351; p. 95-105. The Flash Plate technology is generally described by B. A. Brown et al. in High Throughput Screening (1997), p. 317-328. Editor(s): Devlin, John P. Publisher: Dekker, New York, N.Y.

In the Flash Plate EGFR kinase reaction assay, a kinase substrate consisting of biotinylated poly(L-glutamic acid-L-tyrosine) (poly(GT)biotin), is incubated with the aforementioned protein in the presence of (³³P) radiolabeled ATP. (³³P) phosphorylation of the substrate is subsequently measured as light energy emitted using a streptavidin-coated Flash Plate (PerkinElmer Life Sciences) by trapping and quantifying the binding of the biotin tagged and radiolabeled substrate.

DETAILED DESCRIPTION

The EGFR kinase reaction is performed at 30° C. for 60 minutes in a 96-well microtiter FlashPlate (PerkinElmer Life Sciences). For each of the tested compounds a full dose response 1.10⁻⁶M to 1.10⁻¹⁰M has been performed. IRESSA® and Tarceva™ (erlotinib) were used as reference compounds. The 100 μl reaction volume contains 54.5 mM TrisHCl pH 8.0, 10 mM MgCl₂, 100 M Na₃VO₄, 5.0 μM unlabeled ATP, 1 mM DTT, 0.009% BSA, 0.8 Ci AT³³P, 0.35 μg/well poly(GT)biotin and 0.5 μg EGFR-kinase domain/well.

The reaction is stopped by aspirating the reaction mixture and washing the plate 3× with 200 l wash/stop buffer (PBS+100 mM EDTA). After the final wash step 200 l of wash/stop buffer was added to each well and the amount of phosphorylated (³³P) Poly(GT)biotin determined by counting (30 sec/well) in a microtiterplate scintillation counter.

In the glass-fiber filter technology EGFR kinase reaction assay, a kinase substrate consisting of poly(L-glutamic acid-L-tyrosine) (poly(GT)), is incubated with the aforementioned protein in the presence of (³³P) radiolabeled ATP. (³³P) Phosporylation of the substrate is subsequently measured as radioactivity bound on a glassfiber-filter.
